I-Silicon nitride ceramic enezakhiwo ezinhle kakhulu zomzimba, zamakhemikhali nezomshini

I-Silicon nitride ceramic enezakhiwo ezinhle kakhulu zomzimba, zamakhemikhali nezomshini

I-Silicon Nitride Ceramic yi-ceramic material eyenziwe nge-silicon nitride (Si N₄) enezakhiwo ezinhle kakhulu zomzimba, zamakhemikhali, nezomshini ngakho-ke isetshenziswa kabanzi emikhakheni eyahlukene.

Izici Eziyinhloko: Isisindo Esilula, Ukumelana Nokugqokwa Okuphezulu kanye Nokumelana Nokushisa Okuphezulu.

Izicelo Eziyinhloko: Izingxenye Ezimelana Nokushisa, Ukuguga kanye Nokugqwala.

I-Silicon nitride (Si3N4) iyinto enesibopho esiphezulu se-covalent kanye nesakhiwo sokushisa okuphezulu esisebenza kahle kakhulu emandleni okushisa aphezulu, ukumelana ne-oxidation kanye nokumelana namakhemikhali.

    Ithebula Lezinto Ezibalulekile

    I-Silicon nitride ceramics inezinzuzo ezivelele: ukuminyana okuphansi, ukumelana nokushisa okuphezulu, ukuzigcoba, ukumelana nokugqwala. Dense Si3N4i-ceramics iphinde ibonise ukuqina okuphezulu kwe-fracture, izakhiwo ze-modulus eziphakeme kanye nokuzithambisa, okungaba ukumelana okuhle kakhulu nokugqoka okuhlukahlukene nokumelana nezindawo ezinokhahlo ezingabangela ezinye izinto ze-ceramic ukuba ziqhekeke, ziwohloke noma ziwohloke, okuhlanganisa izinga lokushisa elidlulele, umehluko omkhulu wokushisa, kanye ne-vacuum ephezulu kakhulu.

    Izicelo Eziyinhloko Ze-Silicon Nitride Ceramics

    Onjiniyela bamakhemikhali: I-Silicon nitride ceramics inobulukhuni obuphezulu, ukumelana okuhle kakhulu kokugqoka kanye nokumelana nokugqwala, futhi isetshenziswa kabanzi emikhakheni yobunjiniyela bemishini. Ingasetshenziselwa ukukhiqiza izingxenye ezifana nama-bearings, seals, amathuluzi okusika nama-nozzles emazingeni okushisa aphezulu kanye nesivinini, ihlinzeka ngokusebenza okuhle kakhulu nokuphila isikhathi eside.

    Imboni yezimoto: Ngenxa yokuqina kwezinga lokushisa eliphezulu nokumelana nokugqoka kwe-silicon nitride ceramics, isetshenziswa ekwenzeni izingxenye zenjini yezimoto. Ama-ceramics e-silicon nitride angasetshenziswa ukwenza izingxenye zenjini ezisebenza kahle njengezindandatho ze-piston, ama-cylinder liners nama-valve, okusiza ukuthuthukisa ukusebenza kahle kukaphethiloli nokunciphisa ukukhishwa kwegesi.

    I-Aerospace: Isisindo esilula, amandla aphezulu kanye nokumelana nokushisa okuphezulu kwama-silicon nitride ceramics kuwenza abe yizinto ezifanelekile zokusetshenziswa kwe-aerospace. Ingasetshenziselwa ukukhiqiza izingxenye ezibalulekile ezifana nezingxenye zenjini, ama-turbine blades, izinto zokuhlukanisa ezishisayo kanye nokuvikela okushisayo kwemikhumbi-mkhathi ukuze kuhlangatshezwane nezidingo zokushisa okuphezulu, umfutho ophezulu kanye nezindawo eziyingozi kakhulu.

    Imboni yamakhemikhali: I-silicon nitride ceramics isetshenziswa kabanzi embonini yamakhemikhali ngenxa yokuqina kwayo okuhle kakhulu kwamakhemikhali kanye nokumelana nokugqwala. I-silicon nitride ceramics ingasetshenziswa ukwenza imikhumbi yokusabela kwamakhemikhali, abathwali be-catalyst, imishini namapayipi amelana ne-asidi ne-alkali, futhi ingamelana nemidiya egqwalayo nezimo zokushisa eziphakeme.

    I-Optoelectronics: I-Silicon nitride ceramics inezakhiwo ezinhle kakhulu ze-optical kanye ne-elekthronikhi, ngakho-ke zinezinhlelo zokusebenza ezibalulekile emkhakheni we-optoelectronics. Ingasetshenziselwa ukukhiqiza izinga lokushisa eliphezulu namandla aphezulu ama-fiber amplifiers, ama-lasers, amadivaysi okuxhumana optical kanye neWindows optical... njll., enokudlulisa amehlo okuhle kakhulu kanye nokuzinza kwe-thermal.
